To verify your specific board schematic, check the official database via the Intel Product Specifications Portal using the 6-to-9-digit number printed on the physical circuit board bar code label. Technical Specifications Overview
If you cannot see a clear model name, look for a small white barcode sticker placed on the motherboard body (often on the edge of the board or near the back I/O ports). This sticker contains a code starting with the letters (e.g., AA E12345-XXX ). The AA number is a foolproof identifier that maps directly to a specific specification sheet. 3.
